1676.0. "New chips fix flicker" by JGO::CHAPMAN () Fri Sep 09 1988 10:21

I recently read in a UK magazine (I can't even remember the name, but it is the 
weekly rag devoted mainly to low-end machines/games, and that has a great 
questions page - half the space is usually devoted to correcting last weeks 
mistakes, ie. "it has been pointed out to us that if you make this modication,
your computer will go up in smoke" or "the algorithm we gave for calculating pi
converges after 3 zillion iterations to 4" etc) that Commodore has exhibited
a 2000 with:
	- a 80286 bridge (previously unseen)
	- more interestingly, a new chip set which addresses 1MEG instead of
	  512k, AND FIXES THE FLICKER! - ie produces 400 lines non-interlaced

It was shown working - I believe on a normal CBM monitor (it wasn't too clear 
and I don't have the mag still).

This was the front page headline news. Was I dreaming, could it work? Or is it
fiction of the same quality as the questions and answers?

    You've read about the long awaited 'Enhanced Chip Set' which, as
    you noticed, offers a new 400 line non-interlaced mode.  However,
    there are a few catches...
    
    The new 400 line mode will only support 2 bit planes, and a reduced
    color pallette of 64 colors.  The new mode will also require a
    multisync monitor of at least a VGA or MacII compatible monitor,
    since the horizontal scan rate is doubled to 31.5 KHz.  I strongly
    advise any prospective Amiga buyers to purchase a multisync monitor
    NOW to avoid being surprised later.
    
    The juicy item is the 1 meg of CHIP ram available with the Real
    Fat Agnus chip.  That means even bigger and better animations and
    digitized scores.
    
    Unfortunately, the poor A1000 owners who went out on a limb and
    rescued Commodore won't be able to use the new chipset due to major
    differences in the VSLI chips in the A500/A2000  models.  Unless
    some clever hack can figure out an adaptor scheme.
    
    On a related front, I was speaking to MicroWay in Cambridge MA,
    and was informed  that the A500/A1000 FlickerFixer was being targeted
    for a January release.  However, I did see a blurb in a UK Amiga/ST
    rag for a small de-interlacer card for the A500/A2000.  The box
    was about the size of a pack of cigarettes and had a price of #230.
    Have you seen that ad?  I'd be interested in finding out who the
    manufacturer was.  I don't have access to the magazine that I
    originally saw it in.

    Any ideas on the prices for the new stuff ?
    
    ie multisync monitor = $XXXX
    and new chip set = $XXXX
    
    Thanks
    
1676.3A1000 Flicker Fix ??POLAR::GOSLINGThink KANATA INC.Fri Sep 09 1988 15:4811
       What would a flicker fix look like for an A1000?
       
       - a chip
       - a daughter board
       - a box connected to the video output jack
       - a slap on the side add-on
       - a card requiring an expansion chassis
       - etc.

    The photo I saw was a small, stylish box with an input cable and
    an output cable.  Rather benign looking.  You could actually tuck
    it away out of sight.
    
    My A2000 FlickerFixer is only a 4" x 6" card with a bunch of ram
    chips and a few discreets on it.  A clever person could easily cut
    the real estate in half.

Commodore is coming out with their own multisync monitor.  I heard first
reference to it sometime in the last month.

A 400 scan line non-interlaced display will require a multisync or
bisync monitor.  The current Commodore monitors will not be able
to handle the display.

Actually at the big announcement of the Amiga 2000 and 500 for the Boston
Computer Society, Commodore displayed a 80286 bridge card that they had
flown in from Germany the night before.  They didn't show it working,
though :-).
